To license an iThemes product on your site, you'll go to Settings > iThemes Licensing in your site's dashboard.
The Licensed URL should be the primary URL of this WordPress site. If this is not set correctly, some features may not function as expected. Verify that the licensed URL is correct and proceed to the next step.
Check the boxes to the left of the products you want to license then enter your iThemes username and password below the list of plugins. If needed, you can reset your password here.
Click the License Products button and all of the products you licensed will show along with your username, the product or subscription license, expiration date of the subscription and how many licenses you have remaining.
